Doc Text:	Previously, the system-config-network service did not handle correctly those entries in the /etc/hosts/ directory that were specified only with an IP address and with no host name, which caused system-config-network to fail. This bug has been fixed and system-config-network now works properly in the described scenario.	Story Points:	---

Description Tilman Baumann 2009-08-10 08:55:51 UTC

Description of problem:
system-config-network-gui allows you to save host entries with no ip, hostname or alias.
A entry with for example only a ip will cause system-config-network-gui to fail at next startup.

This entry will for crash system-config-network-gui
cat /etc/sysconfig/networking/profiles/default/hosts
10.33.1.83              # Crashme
10.33.1.84      foo     bar


This problem is fixed in Fedora 11 (and maybe earlier).
It not only does not allow you to save broken entries. It can parse them again and tell you that there is a error without crashing.


Can you please make sure this fix goes into RHEL6 and possibly RHEL5.4.



Version-Release number of selected component (if applicable):

system-config-network-1.3.99.12-1.el5
RHEL5.3

How reproducible:

create the following file with these 
/etc/sysconfig/networking/profiles/default/hosts
10.33.1.83
10.33.1.84      foo     bar

Or save a entry with only a IP no hostname and alias.
